Owner Narrative
My 2021 Chevrolet Suburban experienced a sudden and complete engine failure at approximately 79,000 miles. The vehicle became inoperable and is currently at a dealership pending evaluation. There were no prior warnings indicating an imminent catastrophic failure. A sudden engine failure of this nature presents a significant safety concern, including the risk of loss of propulsion during operation. The failure has been confirmed by the dealership, and no repairs have been authorized at this time pending further review. This complaint is being submitted to document a sudden and severe engine failure and to request evaluation of potential safety-related defects involving internal engine components.
